krandtest {ade4}R Documentation

Class of the Permutation Tests (in C).

Description

Plot and print many permutation tests. Objects of class 'krandtest' are lists.

Usage

## S3 method for class 'krandtest':
plot(x, mfrow = NULL, nclass = NULL, main.title = x$names, ...)
## S3 method for class 'krandtest':
print(x, ...)
as.krandtest(sim, obs, alter="greater", call = match.call(),names=colnames(sim))

Arguments

x : an object of class 'krandtest'
mfrow : a vector of the form 'c(nr,nc)', otherwise computed by as special own function n2mfrow
nclass : a number of intervals for the histogram
main.title : a string of character for the main title
... : further arguments passed to or from other methods
sim a matrix or data.frame of simulated values (repetitions as rows, number of tests as columns
obs a numeric vector of observed values for each test
alter a vector of character specifying the alternative hypothesis for each test. Each element must be one of "greater" (default), "less" or "two-sided". The length must be equal to the length of the vector obs, values are recycled if shorter.
call a call order
names a vector of names for tests

Value

plot.krandtest draws the p simulated values histograms and the position of the observed value.
